Abstract
A method for treating the lower extremity varicose vein combined ultrasonic wave and microwave is provided. The method includes steps of firstly finding the diseased vein by the ultrasonic imaging equipment; and then directly effecting the microwave treatment catheter/needle on the diseased vein; by the concentric thermal coagulation release effect of the microwave to the tissue, instantly generating high temperature with the certain penetration range in a small range for tissue coagulation; and then gradually making the vascular fibrosis; finally making the completely atresia, thus achieving the therapeutic aim. The present invention uses the ultrasonic imaging microwave treatment technique to treat the lower extremity varicose vein disease. It accurately, firmly and thoroughly closes the varicose blood vessel, has the exact effect, small trauma and less pain to patients, less bleeding in surgery, quick recovery, simple operative procedure and no significant complication, is difficult to form the deep venous thrombosis.
